75 Safety and Security
Occupant safety
The 7indicator lamp located in the
center console will be illuminated, except
with the SmartKey removed or in the start-
er switch position0.
Self-test BabySmart
TM without special
child seat installed
After turning the SmartKey in the starter
switch to position1 or2, the
7indicator lamp located in the center
console comes on for approximately
six seconds and then goes out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized
Mercedes-Benz Light Truck Center before
seating any child on the front passenger
seat.
For more information, see “Practical hints”
section (
page 297).
i
The system does not deactivate the
emergency tensioning device.
Warning!G
The BabySmartTM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
passenger front airbag will not deploy only
if the 7 indicator lamp remains
illuminated.
Warning!G
Make sure to check the indicator every time
you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the front passenger seat until the system
has been repaired.
Warning!G
Do not place powered-on laptops, cell
phones, electronic tags such as those used
in ski passes and like electronic devices on
the front passenger seat. Signals from such
devices may interfere with the BabySmart
TM
system. Such signal interference, for exam-
ple, may cause the 7 indicator lamp not
to come on during self-test or be continu-
ously lit, indicating that the system is not
functioning.

Memory function
Memory function
The memory button and stored position
switch are located on the door.
You can store up to three different settings
per SmartKey.
The following settings are saved for each
stored position:
Driver’s seat and seat backrest posi-
tion, head restraint position
Steering wheel position
Driver’s side exterior rear view mirror
position
Passenger-side exterior rear view
mirror positionThe following settings are not key-depen-
dent. They are stored when using the but-
tons on the front passenger door:
Front passenger seat and backrest po-
sition, head restraint position.
These key-dependent memory settings
can be deactivated if desired
(
page 144).
!
Prior to operating the vehicle, the driv-
er should check and adjust the seat
height, seat position fore and aft, and
seat backrest angle if necessary, to
ensure adequate control, reach and
comfort. The head restraint should also
be adjusted for proper height. See also
the section on airbags (
page 63) for
proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the interior and
exterior rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in a properly
secured restraint system that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213
and 210.2.
Warning!G
Do not activate the memory function while
driving. Activating the memory function
while driving could cause the driver to lose
control of the vehicle.

Useful features
Emergency calls
An emergency call is initiated
automatically:
following an accident in which the
emergency tensioning devices (ETDs)
or airbags deploy
if the anti-theft alarm or the tow-away
alarm stays on for more than
20 seconds. See anti-theft alarm sys-
tem (
page 88) and tow-away alarm
(
page 89)
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See below for instructions on
initiating an emergency call manually.Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
EMERGENCY CALL –
CONNECTING CALL
appears in the multifunc-
tion display. When the connection is estab-
lished, the message
EMERGENCY CALL –
CALL CONNECTED
appears in the
multifunction display. All information rele-
vant to the emergency, such as the loca-
tion of the vehicle (determined by the GPS
satellite location system), vehicle model,
identification number and color are gener-
ated.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
When a voice connection is established the
audio system mutes and the message
TELE AID – EMERGENCY CALL ACTIVE ap-
pears in the multifunction display.The Response Center will attempt to deter-
mine more precisely the nature of the acci-
dent provided they can speak to an
occupant of the vehicle.
The Tele Aid system is available if:
it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection
and cellular air time
the relevant cellular phone network
and GPS signals are available and pass
the information on to the Response
Center
i
Location of the vehicle on a map is only
possible if the vehicle is able to receive
signals from the GPS satellite network
and pass the information on to the
Response Center.

Light Truck Center immediately to have the
system checked; otherwise the SRS may not
be activated when needed in an accident.This could result in serious or fatal injury, or
it might deploy unexpectedly and unneces-
sarily which could also result in an accident
and/or injury to you or to others.
